MACHINE 3GB TREATING;- YARNG WITH Application filed June 3, 1924, Serial No.

The present invention relates to that type of machines for continuously dyeing, washing, and otherwise similarly treating yarn in hanks, in which a concentric series of tanks or vats having rotating above them a concentric series of pairs of rollers upon and between which the hanks are suspended. By the rotation of the rollers upon their axes the hanks are continuously run through the liquor in the troughs or vats below, and by the concentric motion of the rollers the hanks are successively transfe "red from one vat to the next through the series. In such machines as they are at present constructed and arranged diiiiculty is experienced to get an uniform dyeing and to prevent the hanks from becoming twisted, entangled, knotted, etc.

These improvements have for their object to overcome. the objections hereinbefore referred to and for this purpose they con sist in the construction and arrangement of devices to lead-off the spent liquor of the hanks which liquor is squeezed out by the co-operating rollers.

In the drawings one form of construction of the device is shown in a. diagrammatical manner.

Figs. 1 and 2 show each a face view of a pair of rollers in different position.

Fig. 3 is a side view thereof.

Two rollers 1, 2 are rotatably mounted on shafts arranged parallel to each other on acommon frame B. Said frame B is rotatably mounted on a vertical shaft and the pairs of rollers 1, 2 move over troughs or tanks arranged in a circle concentric around the axis of rotation of the frame B. The troughs are filled with liquids by which the material is to be treated and the rollers 1, 2 are arranged at such height that the hanks of yarn A hung on said rollers are partly immersed in said liquid. The hanks A are arranged in batches on the rollers 2 which rollers are rotatably mounted in levers 3 journalled in the frame B. The means to move the rollers 2 with reference to the rollers 1 and the means to rotate the rollers 1 by a motor are not shown in the drawing. On the shaft of a roller 1 an arm 5 is loosely mounted projecting downwards and carrying a stud 6. On the stud 6 a double armed lever 7 is rotatably mounted and rigidly fixed to said lever 7 is a shallow channel 10 running parallel to said roller 1. The channel 10 has to guide off the liquid squeezed 717,?29, and in Switzerland July 1, 1923 out from the hanks A by pressing the roller 2 on to roller 1. i To bring'the channel into the position shown in Fig. 1 blocks 9 are adjust-ably fixed to the fixed frame C of the machine and the said blocks project in the path of a roller 8 rotatably mounted on an arm of lever 7. Said roller 8 running over the said blocks 9 tilts the lever 7-from the position shown in Fig. 2 to the position shown in Fig. 1 in which the channel 10 is pressed on to the hank and assumes a position vertically below the point of contact of the rollers 1, 2 in such a manner that the liquid pressed out of the yarn passes over the chan- A squeezed between the rollers 1, 2 acting as the friction member. The pressure point between the rollers 1, 2 is indicated at 11. To keep the hanksin good order two guide rollers 12, 14: are arranged on arms 15 of the frame B. The two guide rollers 12, 14 are driven by belts 16 and 17 from said roller 2, and prevent the hanks becoming twisted or knotted.

In the drawings Figures 1 and 2 and in the detail drawings only one set of rollers is indicated and I will hereinafter limit my description to one such set, this elementary representation and description being adopted for the sake of greater simplicity and clearness, but it will be understood that as many sets of the rollers and accessories as may be required and as are convenient may be employed.

What I wish to secure by U. S. Letters Patent is:

1. In a machine for continuously dyeing, washing and otherwise similarly treating yarns in hanks, pairs of rollers upon and between which the hanks are suspended, of which rollers one of a pair is positively driven, whilst the other with the hanks upon it is driven by roller, and means to lead-ofi the liquid squeezed out by the co-operating rollers from the hank, said means comprising a shallow trough adjustably mounted below the lin of contact of the two rollers.
